Output transformers play an important role in determining the sound quality and performance of a vacuum tube amp. LUXMAN’s classic amplifier products featured OY15 type output transformers with die-cast aluminum housings. These have been redesigned and reproduced with the original shape. The power supply section features a highly stable El type power transformer in tandem with custom designed blocking capacitors yielding steadfast sound quality and excellent drivability.
The main chassis of the MQ-88uC has a dark brown finish, different to the black finish of the MQ-88u. We feel this finish better matches our products with wooden exterior cases. The hairline finished aluminum top panel and matt black aluminum die-cast power transformer housings make for a harmonious match, fine quality and beauty being important to our designs.
